Guidance (or "slow rolling") helps with strong/deep learning and enables opportunities for conversation.
If you trust your boss/coworker, considering letting them continue when they start such discussions.
If you don't trust them or feel frustrated/patronised while they're talking, then you have other issues...
Trust has nothing at all to do with it, nor does ownership as the article implies as I do not own any of the idea's or work I produce for my employer. That is the purpose of my employment, I trade my skills, knowledge and experience for currency.
My employer trusts my boss that is the only Trust that is required, I give my input based on how I see things, if they accept it great, if they want to go another route or use a different idea that is fine as well.
I do not have these types of emotional attachments to my work
I hate being slow rolled to idea or opinion..
If you have criticism about my work come out with it, I am not some delicate little snowflake, if there is better way I want to know.
